LTC2170IUKG-14#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2170IUKG-14#TRPBF is a 14-bit, 25Msps quad analog-to-digital converter (ADC) from Analog Devices. It features four simultaneous sampling channels with serial LVDS outputs and operates on a single 1.8V supply. Key electrical specifications include a typical Signal-to-Noise Ratio (SNR) of 72.8dBFS at 70MHz input, a Spurious Free Dynamic Range (SFDR) of 90dBFS, and an ultralow jitter of 0.15ps RMS. The device offers selectable input ranges of 1VP-P to 2VP-P, internal or external reference options, and supports both shutdown and nap modes for power management.
